MANUFACTURE OF REEDS FOR MUSECAL INSTRUMENTQ.

EPECIPICATION forming part of Letters Patent No. 338,007, dated M en-cl: 1t}, 1886.

Application filed June 25, 1885. Serial X0. 169,702. (No specimens.)

1' 0 all whom it may concern:

Be it known that I, J osIAH D. \VHITNEY, of Brattleborough, in the county of Vindham and State of Vermont, have invented new Improvements in llIanufacture of Reeds for Musical Instruments; andl do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a perspective view of a reed, looking upon the face side; Fig. 2, a longitudinal section through the heel portion of the reed, illustrating the first operation in the formation of the rivets; Fig. 3, the same section after the second operation, the tongue applied, the upsetting or riveting indicated in broken lines.

The object of my invention is to avoid the possibility of the detachment of the reed when once secured to the body; and it consists in first punching the body from the face side,to throw a corresponding projection upon the opposite side, the projection being larger in diameter than the recess punched in the face side, then applying the tongueto the face side over the recesses formed by the punch, and then forcing the metal, which thus forms the stud,through the smaller recesses,thence through the tongue, and riveting them down, and whereby the portion of the stud within the body is of larger diameter than the projecting stud itself, as more fully hereinafter described. I first take the usual body, B,(see Fig. 2,) and upon its face sidethat is, the side to which the tongue is to be applied-and at the usual position for riveting, I apply a punch in size corresponding to the stud to be produced and to the perforation through the tongue, and under pressure form the recesses (1 upon that face side, forcing the metal through the body to form corresponding projections, 0, upon the reverse side,but oflarger diameter than the recesses upon the face side. The best instruments for forming this recess on the face side and projection on the opposite side is apuneh and a die, the die having openings in it corresponding to the larger diameter required for the projections on the reverse side, and the punch, as before stated, of a diameter corresponding to the recesses in the face side, the

body of the reed laid upon the die face side up and in the proper relative position to the openings in the die, and so that the punches when 55 forced to ward the die will produce the recesses on the face side, and the larger diameterprojee tions 0 on the opposite side. This operation substantially separates the stud portion from the body, asindicated in Fig. 2. Then, as the 60 next operation I apply the tongue a upon the face side, as indicated in broken lines, Fig. 2, the heel end over the recesses in the face of the body of the reed, and with itstongue in the proper relation to the slot in the reed; then return the 65 stud portion, formed as before mentioned, and drive it through the heel portion of the tongue, to form the rivets to secure the tongue to the reed. This operation is best performed by means of a punch applied to the projecting 7o in Fig. 3. Then the studs are riveted down up- 8c on the tongue in the usual manner, as indicated in broken lines, Fig. 3. By this 0011- struction the tongues are secured as if by a conical rivet introduced through a hole in the body from the reverse side, the hole itself 8 gradually contracting toward the face side, and the stud of corresponding frustumof-cone shape, so that the stud takes a firm bearing in the body to resist the strain or tendency of the tongue to draw the stud through, and de- 9 tachment of the tongue without first removing the upset or riveted portion of the stud is impossible.

The driving of the studs into the contracted hole in the body makes the firmest possible 9 connection between the stud and the body to hold the rivet in place.

I do not wish to be understood as claiming, broadly, the attachment of tongues to reeds by means of rivets forced from the metal of the body of the reed through the tongue, as such, I am aware, is not new.

I claim The herein-described improvement in the IOU 'formation of said recesses and projections in the reverse direction through the body and consisting in first punching the body Where through the tongue, to form projecting studs the rivets are required from the face side toon the body through the tongue, the said pro- Ward the reverse side, forming recesses on the jecting studs from the face being of smaller face side and corresponding projections on 1 diameter than upon the reverse side, the said the reverse side, but the projections on the I projecting studs riveted upon the tongues, reverse side of larger diameter than the rel substantially as described.

cesses on the face side, then applying the tongue upon the face side of the body Within JOSIAH T the heel end and over said recesses, then forcing the metal of the body displaced in the manufacture of reeds for musicalinstruments,
